and \(\mu \)  and \(\rho \)  are interpreted as the chemical potential and
charge density of the dual field theory [1]}, [2]}. Also
\(\psi _{\pm }=<\mathcal {O_{\pm }}>\)  specifies the vacuum expectation
value of the dual operator \(\mathcal {O_{\pm }}\)  on the boundary.
According to the AdS/CFT correspondence, either \(\psi _{+}\)  or
\(\psi _{-}\)  will act as a condensation operator while the other
will act as a source [1]}, [2]}. In the present work, we
choose \(\psi _{-}=<\mathcal {O}_{-}>\)  and \(\psi _{+}\)  as its source.
Since we would like the condensation to take place in the absence
of any source, we set \(\psi _{+}=0\) . Considering the fact that
\(m^2\)  must satisfy the Breitenlohner-Freedman (BF) bound
[5]}, we set \(m^2=-2\)  [2]}.
